BACKGROUND To compare the clinical and radiological features of intra-/juxta-articular osteoid osteoma and extra-articular osteoid osteoma in skeletally immature patients, paying special attention to the skeletal complications. METHODS Osteoid osteoma in 34 children (22 boys and 12 girls, mean age 10.4 years) was dichotomized according to the location of the nidus as intra-/juxta-articular (1...

BACKGROUND Intra-articular techniques (single and double bundles) are the most widely used procedures for the anterior cruciate ligament reconstruction. Lemaire introduced in 1967 the extra-articular techniques, and combined intra-articular and extra-articular reconstruction, to better restore the stability of the knee. However, the effectiveness of these procedures (intra-articular, extra-arti...

The anterior cruciate ligament (ACL) of the knee is an intra-articular ligament that fails to heal after primary repair. The medial collateral ligament (MCL) of the knee is an extra-articular ligament that heals uneventfully in the majority of cases. Why these two ligaments have such different responses to injury remains unclear. In this article, we address two hypotheses: first, that the histo...

BACKGROUND Local administration of opioids causes effective analgesia without adverse effects related to the central nervous system. After the beneficial demonstration of peripheral opioid receptors in joint synovia, intra-articular opioid injections were used for pain treatment. Clinical studies have reported the safety and efficacy of hyaluronate injection in the shoulder joint of patients wi...

background: an intra-articular distal humerus mal:union: can be disabling. to improve function, reduce pain and/ or prevent further secondary osteoarthritis an intra-articular corrective osteotomy can be considered. herein we present the indications, practical guidelines for pre- operative planning and surgical technique. subsequently, we provide long-term results in a small series.   methods: ...

Post Arthroscopic intra-articular analgesia is a better method to avoid post-operative pain after arthroscopic surgery, thus avoiding the adverse effects of systemic analgesics. In this prospective randomized double blind study conducted on 90 patients, 30 patients in group A received 20 ml of intra-articular saline, 30 patients in Group B received 10 ml of intra-articular saline and 10 ml of 0...

OBJECTIVES To evaluate the efficacy and safety of intra-articular Soaking of high concentration Tranexamic Acid (TXA) in total hip arthroplasty. METHODS From March 2013 to March 2014, 224 patients who underwent unilateral primary THA in our hospital was enrolled in this randomized, prospective double-blinded study. The patients were allocated into two groups according to intra-articular solut...

OBJECTIVE The aim of this experimental study was to evaluate and compare the chondroprotective efficacy of intra-articular hyaluronic acid, tenoxicam and vitamin E in osteoarthritis. METHODS An osteoarthritis model was created by anterior cruciate ligament transection and medial menisectomy in knees of 28 rats. The rats were randomized into four groups; first group served as a control group a...

BACKGROUND Although intra-articular treatment with hyaluronic acid (HA) for symptomatic osteoarthritis has become widely accepted in recent decades, the pattern of its use has seldom been reported. We have explored the epidemiology of intra-articular HA treatment in Taiwan by using the rich data source from nationwide insurance claims. METHODS Taiwan's National Health Insurance (NHI), which c...
